It features a simple front panel with gain and level controls, plus a two-band EQ (±9 dB shelving at 100 Hz and 10 kHz). You get switchable mic/line/Hi-Z inputs, +48V phantom power, polarity reverse, and a 20 dB pad for handling hotter sources. The tube circuit runs on dual 12AX7/6072A tubes, giving you the thick harmonics and natural compression that made the 610 famous.
